Vue 2 reached end of life on December 31, 2023. Since then, the Vue core team has issued no further updates — no bug fixes, and critically, no security patches. The final Vue 2 release, Vue 2.7 ("Naruto"), is the last version that will ever ship. If you're still running Vue 2 in production — and many teams are — every vulnerability discovered from 2024 onward stays open unless you patch it yourself or buy extended support.
Vue version EOL schedule
| Version | End of Life | Status | Risk Score |
|---|---|---|---|
| Vue 2.6 | Jun 30, 2022 | EOL | 70 |
| Vue 2.7 (final Vue 2) | Dec 31, 2023 | EOL | 70 |
| Vue 3.3 | Dec 28, 2023 | EOL | 70 |
| Vue 3.4 | Sep 2, 2024 | EOL | 65 |
| Vue 3.5 (current) | Active | Supported | 30 |
All of Vue 2 is past end of life. Vue 2.7 — the final and most-deployed Vue 2 release — stopped receiving security patches on December 31, 2023. If you're on any Vue 2 release, you're running unsupported, unpatched front-end code that ships to every one of your users' browsers.
Why Vue 2 EOL is a real security problem
It's tempting to treat a front-end framework as lower-risk than a database or OS — it runs in the browser, not your servers. That's wrong in two ways:
- Client-side code is directly attacker-facing. Vue renders untrusted data into the DOM. Framework-level vulnerabilities — XSS through template compilation, prototype pollution in reactivity — execute in your users' sessions.
- The dependency tree ages with it. Vue 2 pins you to Vue CLI, vue-router 3, Vuex 3, and a generation of component libraries that are themselves EOL and often won't run on current Node.js.
Vue 2.7 — the final release
Vue 2.7 was a deliberate bridge release. It backported the Composition API, <script setup>, and improved TypeScript support into the Vue 2 runtime, so teams could start writing Vue-3-style code before migrating. That makes 2.7 the best launchpad for a Vue 3 move — but it's still end-of-life. The security clock ran out December 31, 2023 regardless of API style.
On an older Vue 2 minor (2.6 or earlier)? Upgrade to 2.7 first — smallest possible step, still within Vue 2, and it sets up the Vue 3 migration with far less rework.
Migrating from Vue 2 to Vue 3
Vue 3 is a ground-up rewrite, not a drop-in upgrade. Reactivity moved from Object.defineProperty to ES Proxy, the global API changed (new Vue() → createApp()), and several patterns were removed. The official migration build (@vue/compat) runs Vue 3 in Vue-2-compatible mode and flags each incompatibility.
- Get to Vue 2.7 and latest dependencies first. Update vue-router, Vuex, and component libraries; adopt the Composition API where practical — that code transfers to Vue 3 almost unchanged.
-
Switch to
@vue/compat. It boots your app in compatibility mode and emits a console warning for every deprecated pattern — your migration to-do list, generated from your real code. -
Clear the warnings, one category at a time. Global API (
createApp), filters (removed),v-modelchanges, event-bus removal ($on/$offare gone), functional-component syntax. - Upgrade the ecosystem. vue-router 4, Pinia (successor to Vuex), Vue-3-compatible component libraries. Third-party libraries are usually the biggest blocker.
- Drop compat mode and ship on native Vue 3. Pin to the latest Vue 3 minor and keep current — only the newest minor gets fixes.
Can't migrate yet?
For a large Vue 2 app, migration is a real project — often gated on third-party libraries you don't control. That's a legitimate reason it hasn't happened, but not a reason to ship unpatched XSS. Extended (post-EOL) support maintains security-patched forks of Vue 2 and its ecosystem so you stay protected while migrating on a realistic timeline.
